Based on the advantages of A514 Gr H alloy steel plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A514 Gr H alloy steel plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
Our A514 Gr H alloy steel plate, A572Gr50 plates are produced with thickness up to 100mm. A572Gr50 low-alloy high-strength structural steel plate is widely used in engineering structures, such as construction steel structures, construction machinery, mine mountain machinery, trucks, bridges, pressure vessels. This kind of steel is especially used for those that require good weldability and toughness Construction and construction machinery parts.
A514 Gr H alloy steel plate, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of A514 Gr H alloy steel plate, Chinese grade 45 steel depends on its various properties. A514 Gr H alloy steel plate, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.
The mechanical properties of A514 Gr H alloy steel plate, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.
A514 Gr H alloy steel plate, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s A514 Gr H alloy steel plate domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
